It start runs for about 30 sec and loss power and dies
Symptom indicates fuel starvation but it is best to use something to verify the spark keeps sparking as it dies. If the spark is ok and the spark plug colour is fairly normal and not black and wet, indicating flooding or excess oil, it would be wise to assume fuel starvation and clean out the system thoroughly.

I can almost guarantee it’s not anything to do with his "turbo" or a vacuum leak.
Since I believe this person has GTP, which is supercharged, he is having an issue with his fuel pump resistor. See, GM put a resistor on the fuel pump to make it run at a slowly or faster when the car is pushing boost. I guess their idea was something about fuel econ.
But, when this fails to work the car will die after about 5-10 seconds of running. So there is an easy way to diagnose this problem.
Locate your fuse block under your hood; it’s on the pass side by the battery.
Open the box and find relay #15. Pull out the relay in the attached picture and bend the pin out, reseat the relay and start your car. If your car runs like a champ, you know what the problem was.
And yes, you can run it like this, but I wouldn’t.

two things you can check . look in the trunk on the passenger rear side behind the carpet there is a fuel pump shut off switch make sure the harness wasn't bumped , also there is a fuel pump relay that might be getting hot under the hood near the Fuses on the inner finder well . Good luck

I need to know if your model is throttle body injected or is it the enclosed vortec model 4.3l for that year...
If it is the vortec it is almost a guarantee that your problem relates to a leak at or to the spider injector located inside the intake.
I've fixed a few of these...
